IMPROVEMENT IN wlNoow-BLINDS.

To all whom 'it may concern:

Be it known that I, GEORGE M. FowLER, of Seymour, in the county of New Haven and State of Connecticut, have invented a new Improvement in Window-Blinds; and I do hereby declare the following, when taken in connection with the accompanying drawing and letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawing constitutes part of this specification, and represents in Figure l a perspective View of the inside of the blind, and in Fig. 2 a vertical central section, enlarged.

This invention relates to an improvement in that class of window-blinds in which the slats are made to turn so as to completely close or open the slats, as may be desired, and commonly termed loose-Slat blinds, the object being to dispense with the common blind-staple and also to secure the slats firmly in either a closed or open position. The invention consists in the arrangement of the slats upon a pivot at one edge, having an arm extending into a vertical rod, the said rod arranged at its ends in a sleeve or cylinder, which serves as a guide to support the said rod, but allows its free movement, in which vertical movement the slats are turned to be opened or closed, as the case may be 5 also, in providing such construction with a bolt, whereby the slats may be secured in any desired position.

A A are the stiles; B B, the bottom; C, the top; and D, the middle bar, of common construction. F F are the blind-slats, which, instead of being pivoted so as to turn upon their center, are pivoted at their upper edge, as denoted in Fig. 2, so that in turning to open they swing upon the said center and away from the adjustingbar H, as denoted in broken lines,

Fig. 2. The adjusting-bar H is arranged in a sleeve or cylindrical-bearing, L, on the lower bar, and P on the middle bar, the upper adjusting-bar being arranged in the same manner, the bar moving freely up and down in the said bearings. From each slat an arm, a, extends into a perforation or mortise in the bar H, as seen in Fig. 2, this arm being rigidly fixed to the slats; therefore, as the rod H is drawn down the slats are open, or turned up, as denoted in broken lines, Fig. 2 5 and returned, the slats are closed. By the arrangement of the sla-ts upon a pivot at the inner edge no transverse movement is necessary for the rod H, as is the case in the common construction; hence any ability to arrange the rod Hin fixed bearings. To secure the slats in either position a bolt, d, is arranged through the rod, so that when fully raised it may be thrown into the bea-ring, as seen in Fig. 2,

thus holding the sla-ts firmly down or closed; l

and when open the bolt is inserted at the other extreme in like manner, and may be at any given point between the two extremes. If preferred, the bolt may be xed in the. sleeve or bearing, instead of moving with the rod.

I claim as my invention- 1. The arrangement of the slats F of a window-blind upon a bearing or pivot at one edge, and having an arm from the said edge extending into mortises in the rod H, substantially as described.

2. In combination with the subject-matter' of the first clause of claim, I claim the bolt d to secure the rod H in any defined position.
